We just use the Moultrie programable timer kits with 30 gallon steel drums. Make three legs from 3/4" thin wall metal pipe (electrical conduit from Lowe's, etc) and bolt to the sides of the barrel through the outside "rings". Make the top from 3/4 plywood with either metal flashing to keep the water out or the thin plastic foil type insulation stapled to the top and pulled tight to the cut top of the barrel. Hold the top in place with coated wire pulled through two eye bolts, one on each side of the barrel. Finish off with a rechargable 6 volt battery and a solar charger. Total costs @$100/ unit. Ours have pasted eight to ten years, batteries three to four.
We place mineral blocks out on opposite side of our 100 acres with trail cameras set to catch what we have moving through the area. This really helps with the "regret" at passing a sure shot on a smaller buck. It really opened our eyes to what was actually going on with our area. Including the trespassers that were hunting our stands! The local DNR used the full face pictures to good effect.
